uutils coreutils kill System-wide Process Termination and Denial of Service via Argument Misinterpretation_CVE-2026-35369

{
    "lastseen": "",
    "description": "An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal (SIGTERM) to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massive process termination. This differs from GNU coreutils, which correctly recognizes -1 as a signal number in this context and would instead report a missing PID argument.",
